To all whom it may concern:

Be it known that l, FRANCIS A. WAGNER,

' a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Mechanical rloys, of which l` declare the following to be a full, clear, and exact description.

rlhis invention relates to improvements in toys and has more particular relation to improvements in mechanical toys and devices of the knock-down and build up type for building `on a small scaleI many of the mechanisms andconstructions used on railroads,`

bridges and'in many other. mechanical commercial enterprises.

The principal object of the linvention is to provide devices and mechanism ofsi'mpli-A lied and improved construction for securing an' automatic reciprocation or oscillation of the parts from a continuous rotary motion. f 'A further object is to provide improved combinations of mechanicall elements which may be utilized in different ways for the constructionsof di'erent complete mecha-l nisms.

rlhe'invention also has other objects all of which will be apparent from thefollowing description and claims and froman inspection of the accompanying drawings in which;

Figure 1 represents a side elevation of a railway work car built up from the devices embodyingmy invention; Fig. 2 represents a top'plan view of the same; Fig. 3 represents a front elevation .of the-railroad work car shown in Figs. 1 and 2; Fig. 4 represents a detail perspective view of the rackbar foi' converting the rotarymotion of 'the of apertured plates with flanges, connect ing strips. with slots, link bars with apertures, gear wheels, shafts, collars for attaching parts, bolts andnuts, but 'as these devices are many of them well known in the art I w1ll not enter into any detail descripltion of them here, it being understood that such parts can be combined and 'utilized for the construction of trucks, wagons, railway cars, work cars, bridges, working cranes, dredging machines, and many other mechanical operating mechanisms. f

-As one example f such construction a completed. railwayy crane-'car is shown in Fig. 1. 'lhebody 1 off-the car is builtup in the usual vmanner from the plates and strips of metal bolted together. rlhe traction wheels 2 are fast on axles 3 which areA mounted in the side plates of the car by passing through apertures therein. Each of .these traction wheels, asbest shown in Fig. 5, comprises a hub 4 havingan attaching screw 5, a traction wheel proper stamped to form a tread 6 and rail-'flange 7 and plate 8 apertured at9. 'llhe hub 4 is formed with v a shoulder 10; the reduced part 11 of the hub passing through the aperture in the plate 8 so that the lplate yests against the shoulder. A plate 12 having a lange 13 is also mounted on the reduced part of the hub and this .plate and the traction wheel are secured firmly together byl broaching Vor forcing out the end of the hub as show'n.

'lhe flanges 7 and 13 when the partsare se-- cured together form a pulley wheel thus providing a combined traction and pulley wheel which can be utilized as a traction wheel alone, or as a pulley wheel alone, or

as a traction and pulley wheel at the same l time as shown in Fig. 1. A pinion 14 having an attaching collar 15 provlded with a locking screw" 16 is, in the example shownin Fig.,1, attached to one of the axles 3 and is engaged by the rack' formed on the slotted bar' 17; the rack teeth being formed on an l angular flange. 18 so that they face inward toward fthe slot 19` and the rack -teeth are l thus yheld to engagement with the pinion ,but

the rack bar is free to reciprocate and at the same time rocken the axle as its plane of .operationis changed because of its connection with the aperturedlrotary driving disk 20. The rack bar as s own in Figs. 1 and 4 is .formed with an angularl apertured end 21 through which a journal bolt 22 passes to -pivotally secure the bar at any desired position yon--the disk 20. The apertures 23 6ft-ias disk, it wai be Observed, are-10eme at different distances from its journal rshaft 24 which is mounted in the proper apertures of the side plates` of the car. By this means the rack may be made to have a gi'eater or less throw as desired. As thedisk is rotated' in one direc/tion the rack will be rei move back and forth.

In the example of work car shown a subframe 30 is built up of the-apertured strips -to support short shafts'3l and -32 held in position by collars 33 and each provided with a crown-gear 34. secured to it at its inner end'; the twoA gears facing one another as shown in Fig. 3 and meshing with a pin-- ion 35 upon opposite sides. The pinion 35 is mounted on the upper end of a shaft 36 mounted in the ksub-frame and .its ollice is ,simply to transmit motion from one of the crown-gears to the other and at the same A oscillate in opposite directions.

time reverse the rotation of shafts 31 and 32 so that the parts carried thereby will The shaft 31 is providedwith a pulleywheel- 37 connected by a belt 38 with one of the pulley wheels on the combined traction and pulley wheels, whereby the shafts 31Y and 32 are oscillated first inone direction and then in the opposite direction as the directions of the movements'of the car are reversed. Each of the shafts 3l and 32 is provided with an arm 39 carrying a bucket 40, grappling hook, or any other loading device. These buckets will balance in their operation. 24 is also formed atone end into a crank handle 41 by which the devices can be started or operated without the motor if desired. 1

' In the modified form of my oscillating drive shown in Fig. 6 the rack bar 17a is straight'andris connected to the drive wheel by a pivoted link 42 which may be pivotally connected to the rack bar at different points by different apertures in the baito allow for the proper location of the bar. In this form the bar is reciprocated in straight lines, the link 42 allowing of this action.

While I have shown my devices, for the sake of illustration,built vup into one form or embodiment I do not wish to limit myself to this yform as the devices can with equal facility be built up into many other forms having the peculiar rotary, oscillating and reci rocating movements.

aving thus described my invention what The shafty the driving devices and the driving wheels comprising a reciprocating rack bar actuated by the driving devices, engaging said pinion and guided by the axle of the driving wheels for causing a continuous rotary motion of the driving devices to automatically move tlie driving wheels intermittently t in opposite directions to propel the car first in one direction and then in the other.

2. The combination, with a supporting frame, of adriving shaft mounted therein and provided with a disk, a driven shaft carrying a pinion fixed thereon, a'rack bar connected to the disk and having a slot to receive the ,driven shaft and an angular flange with rack teeth to engage the pinion.

3. rIhecombination, with a toy adapted to travel lirst in one direction and then in the other, ofa suitably mounted driving device, a driven shaft, and a slotted rack bar driven by the driving device and guided by the driven shaft, the teeth on the rack bar being parallel with but ieinoved from the plane ofthe bar, and a pinion fixed to the driven shaft and meshing with the rack bar.

4. The combination, with a stamped out traction Wheel having a tread, and a combined rail and pulley flange, of a separate stamped out disk having a pulley flange which, together with the combined rail and pulley flange, forms a pulley wheel when the two parts are brought together, and means for securing the traction wheel and disk together to form a'combined rail and pulley wheel.

5. A wheel comprising two stamped disks and a uniting part, one of said disks being bent to form a tread and a flange, one side of the flange coacting with the tread to constitute a traction wheel and the other side ythereof to form one wall of a pulley, the

other disk being bent to form the other wall .of the lpulley and the uniting part constituting a hub broaclied at one end to unite the disks together, and means carried by the hub to secure it to a shaft;

6. The combination, with a traction wheel having a tread and a rail flange, of a disk having a flange which, together with the rail flange foims a pulley wheel, and a sliouldered hub passing through the wheel and disk and broached to secure them together.

7 The combination, with a tiaction car, y

of a motor, and connections for moving the car back and forth, pivoted cranes on the car, and devices for oscillating the cranes by movements of the car.

8. The combination, with a traction car, of a rotary motor on the car, gearing for causing tibi-e.caitfto automatically move back ln testimoiiy Whereof aixfiiiy Signatura and lforth when the motory rotates,v cran's in the pes'ence of two witnesses; pivoted -on the' car, and 'gearing connected l FRANK A.
